Active clinical trials for "Bronchitis"

To determine whether an average population of males and females who smoke 10 pack years or more of cigarettes in a primary care setting with chronic bronchitis has already developed significant changes on pulmonary function testing.

To determine whether airway inflammation secondary to inhalation of specific allergens and other environmental agents and functional imbalance of the autonomic nervous system played important roles in asthma and chronic bronchitis.

Study of the energy supply of bicycle ergometric load in athletes and untrained persons with bronchopulmonary diseases (community-acquired pneumonia, bronchitis, chronic obstructive pulmonary disease and acute respiratory viral infections, to justify the timing of the resumption of training, as well as determination of the volume and intensity of physical activity in training and competitive processes.

The purpose of this study is to validate the diagnostic accuracy of a novel host-response based diagnostic tool for differentiating between bacterial and viral etiologies in adult patients aged 18 years and older with clinical suspicion of lower respiratory tract infections (LRTI)

The study does not involve testing of a drug (no treatment intervention). The study will will use spirometry (breathing tests) in subjects of 40 years of age and older with a history of cigarette smoking with chronic bronchitis to check their disease status and whether or not they have COPD. Also, study subjects will be asked to complete a questionnaire (to answer a list of questions on paper).

xTAG RPP assay is a PCR-based assay to detect the presence or absence of viral and bacterial DNA / RNA in clinical specimens (nasopharyngeal swabs). The objective of this study is to establish diagnostic accuracy of the xTAG RPP.

Studying the airway microenvironment in patients undergoing surgical and bronchoscopic interventions for COPD

Surveys administered to subjects who have recovered from COVID-19 to assess how effective their treatment was.

This clinical trial is destinated to evaluate if the periodic screening for deep venous thrombosis by ultrasound of lower extremity in patients with intensive care unit (ICU) patients with COVID 19 impacts on mortality, ICU stay and total lenght of stay in the hospital, along with other outcomes.

This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in December 2012. The purpose of this study is to make a event monitoring to see whether Tanreqing injection is safe and the characteristic and mechanism of anaphylactic reaction used Tanreqing injection in hospitals in China.
